Power Supply Vent Groove Layout for Compact Airflow Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The presence of a start airway for airflow detection in power supply assemblies of electronic vaporization devices occupies a significant amount of space, hindering miniaturization and flat design.
Innovation Solution
The power supply assembly incorporates a first mounting hole with a vent groove on its inner wall and an airflow sensor in air communication with the vent groove, eliminating the need for a separate start airway by using the vent groove for airflow detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate start airway is provided for airflow detection, then airflow detection function is achieved, but device volume increases and miniaturization is hindered
Solution Approach 1:
The patent merges the start airway function with the vent groove structure. The vent groove, which is part of the existing power supply assembly housing, is configured to receive airflow during inhalation, eliminating the need for a separate start airway. This integration allows airflow detection while maintaining compact device dimensions and enabling miniaturization.
2Reliability
If a separate start airway is provided for airflow detection, then airflow detection function is achieved, but device structure becomes more complex
Solution Approach 1:
The patent combines multiple functions into the vent groove structure. The vent groove serves both as a ventilation feature and as the airflow detection channel. By integrating these functions, the structural complexity is reduced compared to providing a separate, dedicated start airway component.
Solution Approach 2:
The vent groove is designed to perform multiple functions: it provides ventilation for the power supply assembly and simultaneously serves as the start airway for airflow detection. This multi-functionality reduces the overall number of components and simplifies the device structure.
